Is it savable

I have 6 eggs in the incubator usually have a good success rate. This time only one has hatched but its really sick. It hatched about 3 hours ago but hasn't even attempted to stand and it mouth just keeps moving. It's umbilical cord is still attached to it and a huge amount of shell. It's still really wet but i discovered it was lying in a puddle so have moved it onto a plastic lid to dry out in the bator. Oh ye 3 hours on it's still blind like when there coming out. Its a light sussex.
